    fzr250 3ln starting problems

    Hey hey

    need a little advice/knowlege reguarding a 3ln fzr250...

    it was put away around a year ago, running like a sack of crap (no power, trouble reving etc) now ive decided its time to get it going..

    replaced the oil, oil filter, air filter, fuel filters, and sealed the carb boots with silicone..yesterday it started but still wouldnt rev happily and today it's lost spark and the fuel pump doesnt turn off after 5 seconds like usual, exup is also doing funny things when kill switch is turned to on..

    im thinking pickup but im not entirely sure how to test it.

    anyone else had this issue?

    my fuel pump didnt turn off until i realised i forgot to turn the fuel tap on lol..

    from my experience, when it was running bad i did a full flush of everything and cleaned the pipes where i could and carb clean was a big difference.

    hope its some sort of help.
